2Plasmonics for solid-state lighting: enhanced excitation and directional emission of highly efficient light sources显示文摘Light sources based on reliable and energy-efficient light-emitting diodes (LEDs) are instrumental in the development of solid-statelighting (SSL). Most research efforts in SSL have focused on improving both the intrinsic quantum efficiency (QE) and the stability oflight emitters. For this reason, it is broadly accepted that with the advent of highly efficient (QE close to 1) and stable emitters, thefundamental research phase of SSL is coming to an end. In this study, we demonstrate a very large improvement in SSL emission (above70-fold directional enhancement for p-polarized emission and 60-fold enhancement for unpolarized emission) using nanophotonicstructures. This is attained by coupling emitters with very high QE to collective plasmonic resonances in periodic arrays of aluminumnanoantennas. Our results open a new path for fundamental and applied research in SSL in which plasmonic nanostructures are able tomold the spectral and angular distribution of the emission with unprecedented precision.Gabriel Lozano Davy J Louwers Said RK Rodrı´guez Shunsuke Murai Olaf TA Jansen Marc A Verschuuren Jaime Gomez Rivas 2013Light(Science & Applications)2013,2,1:8

7Hepatic flow is an intraoperative predictor of early allograft dysfunction in whole-graft deceased donor liver transplantation: An observational cohort study显示文摘BACKGROUND Early allograft dysfunction(EAD)after liver transplantation(LT)is an important cause of morbidity and mortality.To ensure adequate graft function,a critical hepatocellular mass is required in addition to an appropriate blood supply.We hypothesized that intraoperative measurement of portal venous and hepatic arterial flow may serve as a predictor in the diagnosis of EAD.AIM To study whether hepatic flow is an independent predictor of EAD following LT.METHODS This is an observational cohort study in a single institution.Hepatic arterial blood flow and portal venous blood flow were measured intraoperatively by transit flow.EAD was defined using the Olthoff criteria.Univariate and multivariate analyses were used to determine the intraoperative predictors of EAD.Survival analysis and prognostic factor analysis were performed using the Kaplan-Meier and Cox regression models.RESULTS A total of 195 liver transplant procedures were performed between January 2008 and December 2014 in 188 patients.A total of 54(27.7%)patients developed EAD.The median follow-up was 39 mo.Portal venous flow,hepatic arterial flow(HAF)and total hepatic arterial flow were associated with EAD in both the univariate and multivariate analyses.HAF is an independent prognostic factor for 30-d patient mortality.CONCLUSION Intraoperative measurement of blood flow after reperfusion appears to be a predictor of EAD;Moreover,HAF should be considered a predictor of 30-d patient mortality.Pablo Lozano Lominchar Maitane Igone Orue-Echebarria Lorena Martín Cristina Julia Lisbona María Magdalena Salcedo Luis Olmedilla Hemant Sharma Jose Manuel Asencio JoséAngel López-Baena 2019World Journal of Hepatology2019,11,9:4
8New genes emerging for colorectal cancer predisposition显示文摘Colorectal cancer(CRC)is one of the most frequent neoplasms and an important cause of mortality in the developed world.This cancer is caused by both genetic and environmental factors although 35%of the variation in CRC susceptibility involves inherited genetic differences.Mendelian syndromes account for about5%of the total burden of CRC,with Lynch syndrome and familial adenomatous polyposis the most common forms.Excluding hereditary forms,there is an important fraction of CRC cases that present familial aggregation for the disease with an unknown germline genetic cause.CRC can be also considered as a complex disease taking into account the common diseasecommom variant hypothesis with a polygenic model of inheritance where the genetic components of common complex diseases correspond mostly to variants of low/moderate effect.So far,30 common,low-penetrance susceptibility variants have been identified for CRC.Recently,new sequencing technologies including exomeand whole-genome sequencing have permitted to add a new approach to facilitate the identification of new genes responsible for human disease predisposition.By using whole-genome sequencing,germline mutations in the POLE and POLD1 genes have been found to be responsible for a new form of CRC genetic predisposition called polymerase proofreading-associated polyposis.Clara Esteban-Jurado Pilar Garre Maria Vila Juan José Lozano Anna Pristoupilova Sergi Beltrán Anna Abulí Jenifer Muoz Francesc Balaguer Teresa Ocaa Antoni Castells Josep M Piqué Angel Carracedo Clara Ruiz-Ponte Xavier Bessa Montserrat Andreu Luis Bujanda Trinidad Caldés Sergi Castellví-Bel 2014World Journal of Gastroenterology2014,20,8:3

10A high-density, multi-parental SNP genetic map on apple validates a new mapping approach for outcrossing species显示文摘Quantitative trait loci(QTL)mapping approaches rely on the correct ordering of molecular markers along the chromosomes,which can be obtained from genetic linkage maps or a reference genome sequence.For apple(Malus domestica Borkh),the genome sequence v1 and v2 could not meet this need;therefore,a novel approach was devised to develop a dense genetic linkage map,providing the most reliable marker-loci order for the highest possible number of markers.The approach was based on four strategies:(i)the use of multiple full-sib families,(ii)the reduction of missing information through the use of HaploBlocks and alternative calling procedures for single-nucleotide polymorphism(SNP)markers,(iii)the construction of a single backcross-type data set including all families,and(iv)a two-step map generation procedure based on the sequential inclusion of markers.The map comprises 15417 SNP markers,clustered in 3 K HaploBlock markers spanning 1267 cM,with an average distance between adjacent markers of 0.37 cM and a maximum distance of 3.29 cM.Moreover,chromosome 5 was oriented according to its homoeologous chromosome 10.This map was useful to improve the apple genome sequence,design the Axiom Apple 480 K SNP array and perform multifamily-based QTL studies.Its collinearity with the genome sequences v1 and v3 are reported.To our knowledge,this is the shortest published SNP map in apple,while including the largest number of markers,families and individuals.This result validates our methodology,proving its value for the construction of integrated linkage maps for any outbreeding species.Erica A Di Pierro Luca Gianfranceschi Mario Di Guardo Herma JJ Koehorst-van Putten Johannes W Kruisselbrink Sara Longhi Michela Troggio Luca Bianco Hélène Muranty Giulia Pagliarani Stefano Tartarini Thomas Letschka Lidia Lozano Luis Larisa Garkava-Gustavsson Diego Micheletti Marco CAM Bink Roeland E Voorrips Ebrahimi Aziz Riccardo Velasco François Laurens W Eric van de Weg 2016Horticulture Research2016,3,1:3
11Relativistic-intensity near-single-cycle light waveforms at kHz repetition rate显示文摘The development of ultra-intense and ultra-short light sources is currently a subject of intense research driven by the discovery of novel phenomena in the realm of relativistic optics,such as the production of ultrafast energetic particle and radiation beams for applications.It has been a long-standing challenge to unite two hitherto distinct classes of light sources:those achieving relativistic intensity and those with pulse durations approaching a single light cycle.While the former class traditionally involves large-scale amplification chains,the latter class places high demand on the spatiotemporal control of the electromagnetic laser field.Here,we present a light source producing waveformcontrolled 1.5-cycle pulses with a 719 nm central wavelength that can be focused to relativistic intensity at a 1 kHz repetition rate based on nonlinear post-compression in a long hollow-core fiber.The unique capabilities of this source allow us to observe the first experimental indications of light waveform effects in laser wakefield acceleration of relativistic energy electrons.Marie Ouille Aline Vernier Frederik Bohle Maimouna Bocoum Aurelie Jullien Magali Lozano Jean-Philippe Rousseau Zhao Cheng Dominykas Gustas Andreas Blumenstein Peter Simon Stefan Haessler Jerome Faure Tamas Nagy Rodrigo Lopez-Martens 2020Light(Science & Applications)2020,9,1:3

17Hydrogels for neuroprotection and functional rewiring: a new era for brain engineering显示文摘The neurological devastation of neurodegenerative and cerebrovascular diseases reinforces our perseverance to find advanced treatments to deal with these fatal pathologies.High-performance preclinical results have failed at clinical level,as it has been the case for a wide variety of neuroprotective agents and cell-based therapies employed to treat high prevalent brain pathologies such as stroke,Alzheimer’s and Parkinson’s diseases.An unquestionable reality is the current absence of effective therapies to neuroprotect the brain,to arrest neurodegeneration and rewire the impaired brain circuits.Part of the problem might arise from the lack of adequate in vitro and in vivo models and that most of the underlying pathophysiological mechanisms are not yet clarified.Another contributing factor is the lack of efficient systems to sustain drug release at therapeutic concentrations and enhance the survival and function of grafted cells in transplantation procedures.For medical applications the use of biomaterials of different compositions and formats has experienced a boom in the last decades.Although the greater complexity of central nervous system has probably conditioned their extensive use with respect to other organs,the number of biomaterials-based applications to treat the injured brain or in the process of being damaged has grown exponentially.Hydrogel-based biomaterials have constituted a turning point in the treatment of cerebral disorders using a new form of advanced therapy.Hydrogels show mechanical properties in the range of cerebral tissue resulting very suitable for local implantation of drugs and cells.It is also possible to fabricate three-dimensional hydrogel constructs with adaptable mesh size to facilitate axonal guidance and elongation.Along this article,we review the current trends in this area highlighting the positive impact of hydrogel-based biomaterials over the exhaustive control of drug delivery,cell engraftment and axonal reinnervation in brain pathologies.Rocío Fernández-Serra Rebeca Gallego Paloma Lozano Daniel González-Nieto 2020Neural Regeneration Research2020,15,5:2
